Phenol → Diphenyl carbonate

Participants

Reaction Steps

In a planar-section pot with flow-spoilers, a blower/stirrer and reflux condenser, 0.75 mol/h of phosgene was continuously bubbled into 141 g (1.50 mol) of phenol in the presence of 14.1 g (10 wt. % with reference to phenol) of a powdered aluminium oxide 507-C-I (neutral) from CAMAG. After about 2 h reaction time, the phenol conversion was 41%, wherein 66 g of diphenyl carbonate were formed. The selectivity to give carbonate was >99%.
